He’s right! Trump is walking a lot to all of the events and standing for long periods of time - and, yes, using lots of arm movements! His energy is amazing.
It’s really no joke. It might sound silly, but one time when I was a little bored hearing the same stuff over and over from his stump speech, I tried to mirror his arm and hand movements. Honesty, my arms were tired in less than 5 minutes and he went on for an hour of continual gesturing.
Seriously the man gestures A LOT:
